GUARD FOR INCANDESCENT LAIVIPS.`

SPECIFICATION forming part of Letters Patent No. 763,009, dated June 21, 1904.

Application filed December 215 1903. Serial No. 185,922. (No model.) l

To raf/ZZ roh/071 t 171,114/ concern.-

Be it known that I, J ARIS W. MATTHEWS, a

citizen of the United States, residing at Bridgel ing guard for incandescent lamps, which shally comprise two rcsilientlyconnected halves adapted to be easily and quickly sprung into place and which when in place will hang from the top of' a lamp-socket, so that it will not drop ofi' and cannot be pulled od.

A further object of the invention is to produce a guard for incandescent lamps, which shall be firmly supported on the socket in such a manner that the guard and the lampbulb cannot come in contact with each other, thereby preventing breakage of the bulbs.

A further object of' the invention is to produce a guard for incandescent lamps, which shall be integralwthat is, have no separable part---may be easily attached and removed at any time, but which when once attached need never be removed in ordinary use, as the two halves may be readily sprung apart to permit a lamp-bulb to be cleaned or a lamp to be removed or attached or the socket to be repaired.

With these and other objects .in view I haveV devised the simple and novel incandescent lamp-guard, of which the following descripthe manner in which they are connected to.

gether is unimportant so far as the principle ofl the invention is concerned.

10 denotes an incandescent-lamp bulb and 11the socket, which may be described briefly as having a hub 12 at its upper end and a re-4 duced diameter lat its lower end, as at 13, it

`being, obvious, however, that the style or make of the bulb or the socket are wholly lunimportant so Jfar as the principle 'of' the invention is concerned. A and B indicate the two halves of the guard, which are connected 'at the top only by an open spring-band 14.

For convenience -I indicate the opening in the band by 15. e

16 denotes main frame-wires, which may be made continuous with band 14. If made in one piece of' wire, the center of the piece will be` the portion of the band opposite to the opening. From the opening the ends of' the pieces of wire when formed to shape curve downward andoutward and then inward to inclose the socket, then curve downward andy outward, then around and upward again, forming a loop to inclose the lamp-bulb, then up- ;Ward, outward, and inward again to inclose the socket, the upper ends of said frame-wires being connected to spring-band 14, as at 17. 18 denotes half-bands, the ends of which are connected to the opposite sides of the main frame-wires, as at 19. These half-bands .when the guard is secured in place grip the reduced diameter 13 of the socket firmly and in connection with spring-band 14 hold the guard in place thereon, so that in use the guard is perfectly rigid on the socket and the bulb cannot come in contact therewith. l 2O indicates frame-wires, the opposite ends of' which are connected to main frame-wires 16 and tohalf-bands 18, as at 21, so that the two halves form together a complete/cage, which readily understood Jfrom the drawings. To attach in place, it is simply necessary to detach the catch and open out the halves ot' the guard, so that they will inclose the bulb of a lamp and spring-band 14 about hub l2. rJhen by engaging the catch the guard is firmly locked in place. sert one in place, it is simply necessaryto open out the halves of the socket, but not to detach band 14 lroin the hub.

Having thus described my invention, I claim- 1. An incandescent-lamp guard comprising two halves connected together by an open spring-band, said band being arranged to removably engage the hub of a lamp-socket so that the halves may be separated to attach or remove a lamp without detaching the band from the hub of a socket.

2. An incandescent-lamp guard comprising two halves connected together by an open spring-band which is arranged to removably engage the hub of a lamp-socket, said halves consisting of main frame-wires connected to the open spring-band, half-bands connected to the main frame-wires and arranged to grip the lower end of a lamp socket and other frame-wires connected to the half-bands and to the main framewires.

3. An incandescent-lamp guard comprising two halves connected together by a springband having an opening and arranged to removably engage the hub of a lamp-socket` said halves consisting orl main frame-wires extending from the band and curved downward and then upward so as to inclose the socket and bulb of a lamp, the other ends of said wires To clean or remove the lamp or to in-v being' connected to the spring-band, halfbands whose ends are connected to the main framejwires and which are arranged to grip the lower end of a lamp-socket and other framewires whose ends are connected to the halfbands and to the main frame-wires.

4. An incandescent-lamp guard comprising two halves resiliently connected to a springband which is arranged to engage the hub of a lamp-socketso that the guard will hang from the top of the socket and the halves may be opened to permit the attachment or removal of a lamp without detaching the band from the hub.

5. An incandescent-lamp guard comprising two halves resiliently connected to a springband which is arranged to engage the hub of a lamp-socket, each half being provided with a half-band arranged to grip the lower end of a socket and a catch for connecting the lower ends of the halves together.

6. An integral lamp-guard comprising a spring-band arranged to engage the hub of a lamp-socket, two halves depending from said band each consisting of main frame-wires, half-bands connected thereto and arranged to grip the lower end of the socket and other frame-wires connected to the half-bands and to the main frame-wires and a catch for connecting the lower ends of the halves.

In testimony whereofI aix my signature in presence of two witnesses.
